base of the Ive-apodeme L2 extends to the right to form a curved plate-like sclerotisation 

 (fig.212-214). The large lobe via, with sclerite L4G in its ventral wall (fig.205), is the 

 ventralmost part of the left complex. 



L4K consists of a plate-like, dorsoventrally curved posterior and a bulge-like (nla in 

 fig. 206, 209; veiled by membrane in fig. 208) anterior part (fig. 209, 210), which are only 

 narrowly connected (fig.205). The dorsal wall to the right of L4K is membranous; its 

 central part is depressed ventrad and anteriad (pne in fig. 208, 209). The hla-hook is 

 evaginated from the left posterior wall of the left complex (fig. 2 10, 212). The distal half 

 of hla is sclerotised by L3, which is rather weak except for its distalmost part. The basal 

 membranous half of the hla-hook (30 in fig.210-212) can be introverted and hla can thus 

 be deeply retracted into the left complex (this state is shown in the figures). To the right 

 of the hla-base the posterior wall of the left complex folds inwards (fpe in fig.210-213) 

 - separating the area of hla from the area dominated by L2 (fig.211). 

 The Ive-apodeme has its entire dorsal wall (fig. 210, 211) and the margins of its ventral 

 wall (fig.211, 225) sclerotised by L2. The sclerotised cuticle is considerably thickened 

 (cross-sections in fig. 21 1-215). The top of the Ive-apodeme and the nla-process are firmly 

 connected (two areas of the internal surface of the cuticle adhere to each other). The Ive- 

 apodeme is the narrow anterior part of a Ive-pouch, which posteriorly expands to the right. 

 At the base of the Ive-apodeme, L2 forks into a left and a right branch (immediately 

 posterior to the cross-section through Ive in fig.213). 



The left branch bears a node-like apodeme (29 in fig. 2 12, with a tuft of fine cuticular 

 threads) and forms the sclerite-ring mentioned above (fig. 21 1-213). This ring is slightly 

 sunken anteriad into the left complex; the cuticle within the ring is evaginated to form 

 the processes paa and pda, which are both sclerotised in their ventral walls only (fig. 209, 

 214; the sclerotisations of both are connected with the basal ring). The membrane 31 in 

 fig.211 -2 14 is the area of contact between the bases of paa and pda (cut through in 

 fig. 2 14). Apart from L2 (dorsal part of the ring, paa-sclerotisation), L4 also contributes 

 to this structure (L4N: ventral part of the ring, pda-sclerotisation). The left branch of L2 

 has another posteriad-directed extension on its ventral side (28 in fig. 214, 215) which lies 

 in the dorsal wall of another process (gta in fig.215, 216). The sclerotised cuticle of the 

 left L2-branch is thickened in most of its parts (cross-sections in fig. 212-215). 



The right branch of L2 broadens and extends far to the right, where it curves dorsad 

 (fig.212-214). Posteriorly this upcurved part extends somewhat back to the left and is 

 involved in some complicated cuticular foldings (near 32 in fig.211, compare fig.209-213). 

 Posterodorsal to the right L2-branch there are some additional membranous in- and 

 outfoldings (fig.210-213).
